Abstract. The definition and numerical calculations of the boundaries of transition zones in planar W-fibers are given. In particular, a calculation was performed for a W-fiber with parameters that allow for a single-mode regime in a wide range of wavelengths (1.55 µm ≤ λ ≤ 3µm). It is shown that the sizes of the considered transition zones at the cutoff frequencies of the main, first odd and second even modes significantly depend on the geometric and optical parameters of the W - fibers. These circumstances are important to consider in the selection
of the parameters W-fibers in order to ensure that they have a stable single-mode or multimode operating condition, the necessary field concentration and effective filtering of the leaking modes.Key words: planar five – layer W-fiber, dispersion relation, cutoff frequency, transition zone, interlayer refractive index, outer transverse wave number, leaking modes.
Financing: The work was carried out within the framework of the state assignment of the Kotelnikov Institute of Radio Engineering and Electronics of the Russian Academy Sciences.
